I completely agree with that.
OP, you should be doing a lot of ab bracing movements to bring that strength up and integrating it properly into compound lifts. Your core shouldn't fail if you want to get as strong as possible and reduce chances of injuries.
Breathing paused squats hit my abs the hardest. You have to brace properly while maintaining a neutral spine. Take deep breaths until you feel it. This helped me learn how to brace using a compound movement. For an isolation exercise, I did hollow holds to build the mind-muscle connection.
